The reimbursement for procedures using moderate (conscious) sedation has changed significantly as of January 1, 2017. Due to the increasing use of anesthesia services to provide moderate sedation during endoscopy, the Centers for Medicare & Medicaid Services made the decision to remove work relative value units from many of the services requiring moderate sedation, including the bronchoscopy codes. If a bronchoscopist provides moderate sedation to a patient without using anesthesia services or another qualified provider, that work (and revenue) can be reclaimed by using the relevant codes. An understanding of the recent changes in coding and billing is essential for appropriate reimbursement.

Mortality related to severe-moderate and severe ARDS remains high. We searched the literature to update this topic. We defined severe hypoxemic respiratory failure as Pao2/Fio2 < 150 mm Hg (ie, severe-moderate and severe ARDS). ⋯ Profound refractory hypoxemia (Pao2/Fio2 < 80 mm Hg) after PEEP titration is an indication to consider extracorporeal life support. This may necessitate early transfer to a center with expertise in these techniques. Inhaled vasodilators and nontraditional ventilator modes may improve oxygenation, but evidence for improved outcomes is weak.

Evidence from longitudinal studies has reported contradictory results regarding the association between OSA and hypertension. In a previous analysis of the Vitoria Sleep Cohort, the relationship between OSA and the risk of developing hypertension was evaluated and no independent association after adjustment for confounding factors was found. In the present study, a post hoc analysis to assess the association between OSA and incident stage 2 hypertension (systolic BP ≥ 160 mm Hg and/or diastolic BP ≥ 100 mm Hg) was made on the basis of sex differences. ⋯ The results suggest an association between moderate and severe OSA, and the incidence of more severe forms of hypertension occurring in men but not in women. However, because this is a community-based study, the women's population characteristics may differ from women usually seen in sleep-disorders clinics.

Case Reports
A 63-Year-Old Woman With Neurofibromatosis Type 1 and Pulmonary Hypertension With Worsening Hypoxemia.
A 63-year-old woman with a history of neurofibromatosis type-1 (NF-1) and pulmonary arterial hypertension (PAH) thought to be secondary to the NF-1 presented with a few weeks of worsening dyspnea on exertion. She took no medications other than sildenafil for her pulmonary hypertension (PH). ⋯ She had previously worked as a waitress. Her mother and her brother had NF-1 but no PH or lung disease.
